Maybe Scalise wants McCarthy to be the face of losing this November so he can come back in a few years when the GOP might take back the House.
But Ryan will still be Speaker in November. He just said he's not leaving until his term ends in January. So how will McCarthy be "the face of losing this November" in that case?
If November ends up being the bloodbath-tsunami we think it will be, I’m telling you the remaining GOP caucus, which will likely be more conservative on average, will blame Paul Ryan and his crew. By bowing out Scalise makes it clear McCarthy is the Paul Ryan heir apparent, and he will be the face of the purge. Meanwhile Scalise puts a little (fake) distance between himself and Ryan so he can be the chosen one for the new House GOP.
Bottom line, I’d bet good money that McCarthy won’t be the top GOP House member for very long if we have Speaker Pelosi come January.
